1.	Which statement is true about the graph shown below?
		A.	The domain is {-3, 2, 4}.	B.	The relation is a function.
		C.	The relation is not a function.	D.	The range is {-3, -2, 0, 1}.
		Hint
	2.	Choose the relation that is a function.
		A.		B.
		C.		D.
		Hint
	3.	Given the function f(x) = x2 + 9, find f(-3).
		A.	18	B.	0
		C.	6	D.	12
		Hint
	4.	Find the domain of the relation shown in the graph.
		A.	{0, 1, 2, 3}	B.	{-2, -1, 1, 2, 3, 5}
		C.	{-3, -2, -1, 0, 1, 3}	D.	{-3, -2, -1, 0, 1, 2, 3, 5}
		Hint
	5.	Is the relation shown in the graph a function? Why or why not?
		A.	No, the relation contains the ordered pairs (3, -1) and (3, 2).
		B.	Yes, the ordered pairs (-3, 2), (-1, 1), and (3, -1) form a straight line.
		C.	No, the relation contains the ordered pairs (0, -1) and (3, -1).
		D.	Yes, the relation contains very few ordered pairs.
